2 Claims.

This invention relates to a clamping device. In the preferred embodiment of the invention, the clamping device is shown on a wire bundle clamp. v

In electrical installations, of either permanent or temporary charactenwires are strung along walls or any supporting structure. At necessary at the point indicated as P. This pressure relieves the tension that holds the edge of hole I in groove 8, and portion 8 springs out of engagement with the stud. Portion 3 readily slides over the stud. The critical feature of this device is the calculated misalignment of center lines of holes 6 and I.

intervals, the electric wires are caught up in a,

bundle and secured to a supporting structure. It is often necessary to remove the clamp to add new wires to the bundle or remove wires from the bundle. For this reason, a clamp having an and in which like numerals refer to like parts.

- In the drawing:

Figure 1 shows a perspective view 01' the wire bundle clamp, embodying the invention.

Figure 2 shows a planview oi the same. Figure 3 shows a side view of the clamp. Figure 4 shows the clamp in an operative position ona mounting stud.

Figure 5 illustrates another application of the clamping device.

Figures 6 and '1 illustrate the post with a nail and wood screw adaptation.

The clamp shown in the drawing is formed of a strip 01 metal I which may be either steel or aluminum alloy. Portions 2 and 3 01' the clamp have holes which are in substantial alignment.- Hole III in portion I permits the mounting of that portion of the clamp securely on a structural member 4, by any means such as stud 5. Hole I, in clamp portion 3, slides over the stud due to its alignment with hole Hi in portion 2. Hole I in clampportion I is axially misaligned with hole, as shown in- Figures 2 and 3. It can readily be seen from Figure 4, that hole 6 will slide over-the studwhile the edge of hole I will tightly engage the stud, when forced over the stud, and comes to rest in a groove 8 oi. the stud. Only slight pressure is required on portion 8 to force hole 1 over the stud and the resiliency oi the metal causes the necessary clamping action of portion I in groove I. To release the clamp it is merely necessary to exert slight pressure Portion ll acts as a spacer to prevent the load on the clamping device from forcing portion 3 into contact with portion 8, which might act to spring the edge of hole 1 out of the groove in the stud.

The above described application of the securing device to a wire bundle clamp is intended to show the utility of the device. It shouldbe understood that the securing device is capable of many applications.

Figure 5 illustrates another typical use where it is desired to secure two members together. The

post or stud I2 would be mounted on member l3 and the securing device I on i3.

The action of the device is similar to that described above.

Figures 6 and 7 show posts [5 and IS with nail and screw adaptations l1 and It for securing the same to wooden structures.

It is to be understood that certain changes, alterations, modifications, and substitutions can be made without'departing from the spirit and scope of the appended claims.

I claim as my invention:

1. A clamping device comprising a strip oi resilient material having a looped supporting portion secured at one end to a supporting surface by a stud having a neck portion and a head portion, the other end-of said strip being bent to form a U-.-shaped portion, said formed end of said strip having the end thereof bent to form spaclng means to prevent contact between the sides of said U-shaped portion, said sides of said U-shaped' portion having holes formed therein for mounting over said stud, said holes being mis- .aligned to cause a clamping action on the stud alignedto cause a clamping action on said stud by the edges of said holes.
